A group of space explores from the Marchante Space Corp have landed on an unknown planet. In order to leave they must find the escape velocity needed to get into orbit. The mass of the planet is 1.7 x 1025 kg and has a radius of 6,965 km. Find the needed velocity to get into orbit. Give your answer in: km/s.

it is called kinetic energy

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
